77° on Nov. 15, 1993, the hottest reading for this week of the year since 1912. Next is 74° in 1973.
Laurys Station’s center stands about 380 ft above sea level. Within three miles the land runs from 300 ft to 800 ft, a difference of 500 ft: hilly country. The highest named summit within 15 miles is Bear Mountain, about 1,670 ft, 14 miles northwest.
Under the town center the state geologic map shows Graywacke and shale of Martinsburg Formation, from the Ordovician, 445 to 487 million years old.
The section below crosses 11 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 15×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, slate. Age: Ordovician, 445 to 487 million years old. About 6 mi of the line.
Shale. Age: Ordovician, 445 to 487 million years old. About 5 mi of the line.
Limestone, dolostone. Age: Ordovician, 445 to 487 million years old. About 5 mi of the line.
Limestone. Age: Ordovician, 445 to 487 million years old. About 3 mi of the line.
Dolostone, limestone. Age: Cambrian, 487 to 542 million years old. About 1 mi of the line.
Black-shale. Age: Early Devonian to Middle Devonian, 384 to 422 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 5 smaller units along the line are not listed.

A raindrop that lands in Laurys Station reaches Delaware Bay and the Atlantic Ocean by way of the Lehigh and the Delaware: about 180 river miles.
150 miles of the trip are on the Delaware.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Laurys Station; river miles along the main stem, rounded.
Laurys Station has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 22° in January. A normal year brings about 33 inches of snow; with the rain, that comes to about 47 inches of water.
On November 14 Laurys Station normally reaches 54° and falls to 34°. The record high is 73°, in 1993; the record low 17°, in 1986. The most rain on this date, 2.41 in, fell in 1972.
